When I run my app I'm getting this error:

The error is telling you the problem. You've not got a setter for
title in the PageWrapper component. You choices are:
a) do away with the carrot symbol and provide getter/setter methods
in your components
b) override WOComponent#synchronizesVariablesWithBindings and
return false (the default is true which requires a setter/getter
for each key .. or, for those less inclined to proper
encapsulation, a public variable)
Thank you very much for the assistance. It runs and works. But...
when doing (a) I get the compile-time error:
"'title' must be bound to a settable variable"
If it runs and works - then that's just a problem with the version of
WOLips you're using. Either that or you've only got <wo:PageWrapper>
and you've not bound title.
I think I'm having installation issues. I am anxiously awaiting a
new combo installer. :-)
Not necessarily - WOLips aint without its warts - like any software
really (especially where Eclipse is concerned) :-)
